Marley29 Posted November 1, 2010 Report Share Posted November 1, 2010 Hi, Just a question for any plumbers out there or people that may have had the problem before. When I flush the toilet there is a very loud huming/vibrating noise which is made even worse if you turn on any of the taps. Its been happening for a couple of weeks now and I want to find out whats causing it, in order to sort it out. Once the toilet has filled up with water again it stops. I'm guessing its to do with pressure or something :blink: Any ideas??? Thanks in advance, Mick Quote Link to comment Share on other sites More sharing options...
vampire Posted November 1, 2010 Report Share Posted November 1, 2010 Its called 'water hammering' and it is to do with pressure/air or incorrectly fitted pipe work,have you had any alterations recently :blink: Quote Link to comment Share on other sites More sharing options...
Doc Holliday Posted November 1, 2010 Report Share Posted November 1, 2010 (edited) It will be your ball valve. You may have one of the old ball and arm types or one of the newer quick fill types, something like torbek or hush flow. I generally replace them as it tends not to be worth faffing about with parts. Try taking the lid off the cistern and instigating the noise with taps then try lifting the arm/float to see if it stops it.

Hucky Posted November 1, 2010 Report Share Posted November 1, 2010 You could try running the cold taps full bore and see if that clears the air (if its air in the system), or lift the cystern lid and hold the ballcock to see if its that (if you hold it it will stop it vibrating).

cheekychappy Posted November 1, 2010 Report Share Posted November 1, 2010 its pressure related go to your stop cock and just turn it down a little to restrict the flow if the toilet has a ball fix valve on the water pipe to it close that a little as it wil do the same thing, nothing to do with air its pressure Quote Link to comment Share on other sites More sharing options...

I have just taken the lid of the cistern and faffed with the ball and arm and it has stopped making the noise. It may start up again but for the time being you have saved me a few quid Many thanks for the advice :blink: This forum is so useful Quote Link to comment Share on other sites More sharing options...

jacksdad Posted November 1, 2010 Report Share Posted November 1, 2010 Its called Pipe Hammer...probably caused by the clocks going back... I'm a qualified plumber, so I know best Really it's usually caused my a valve (Sink tap, WC etc.) 'slamming' shut and sending a shock wave into the pipe which then resonates and makes a racket. An air pocket will actually damp it out, not cause it! Not just noisy but can break weak joints as well, so must be sorted asap, if it keeps happening change the WC ball valve, as you have identified it as the culprit, if it gets worse you may have to fit a hammer arrestor, basically an air pocket that damps the shock down. Another source is often a new washing machine or dishwasher, as the valves are very strong :blink: Quote Link to comment Share on other sites More sharing options...
magman Posted November 1, 2010 Report Share Posted November 1, 2010 :blink: Some great answers there boys and doc i will bet it's not a torbek or hush flow Quote Link to comment Share on other sites More sharing options...
Doc Holliday Posted November 1, 2010 Report Share Posted November 1, 2010 :blink: :good: Some great answers there boys and doc i will bet it's not a torbek or hush flow What care you to wager, Sir? I have known those hydro flow (sorry, not hush flow but then I do have man flu) to be troublesome in that department although they are usually more reliable than the old arm and float type. They usually do emit a kind of high pitched whining noise. Something similar to when you switch off listening to the Mrs but you still hear her, if you know what I mean (don't tell her I said so) Quote Link to comment Share on other sites More sharing options...
magman Posted November 1, 2010 Report Share Posted November 1, 2010 Tor beck and the like normally suffer with the clunk , its more than likely a relaxed washer not returning therefore the part that connects with the arm to washer vibrates causing the water hammer Quote Link to comment Share on other sites More sharing options...
Doc Holliday Posted November 1, 2010 Report Share Posted November 1, 2010 Ah ha! Then you haven't experienced them whining when starting to fill. They'll do that sometimes, sincerely The "Clunk" is normally alleviated with the little corkscrew thingy they give you with them (assuming it hasn't fallen out of the packaging). I'm off home now as I'm feeling the need to try & treat my man flue with some decent whisky (and copiously). Quote Link to comment Share on other sites More sharing options...

Next look for any pipes which are loose near the appliances and clip them up. Good luck. Blackpowder Quote Link to comment Share on other sites More sharing options...
